Hello @clh2022 and welcome to Mayo Clinic Connect. I am so sorry to hear that you have been going through this for 9 months. I wanted to connect you with @julesmango and @robinholly who are part of an existing discussion on long-haul to see if they could share some more information with you based on their experience. You can also see an article that was posted if you click on the reply button and scroll up to the top of the discussion.

While we wait for them to join, can you share what you have tried and if anything provides even moderate relief?
